Properties of rarefied plasma flows in an arc-jet
- Laboratoire d`Aerothermique, Meudon (France)
A DC arc-jet is used at the Institute of Electric Power Engineering at Poznan to produce stationary plasma flows at low pressure with argon or nitrogen. The plasma source contains a thoriated cathode and a segmented anode with a cylindrical channel (diameter 6 mm) for the arc. The arc is ignited by a high voltage (8 kV) and the current of the established arc is in the range 40-300 A. The gas is injected in the chamber of the plasma source with a vortex movement and the mass flow rate is between 0.05 and 1.1 g/s corresponding to a specific enthalpy between 10 and 20 MJ/kg. The expansion of the plasma flows is obtained in a chamber with a diameter of 115 mm and a length of 800 mm for the first zone made of quartz. The static pressure in the chamber is between 0.1 and 500 Torr.
